[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a liquid crystal display screen cleaning device, comprising a housing 1 and a support frame 2. A connecting frame 3 is fixedly connected to the side of the housing 1, and a fixed frame 4 is slidably connected to the side of the housing 1. A movable plate 5 is slidably connected to the top of the fixed frame 4, and a buffer assembly 6 is installed at the bottom of the movable plate 5. A rotating plate 8 is rotatably connected to the top of the support frame 2, and a periodic rotation assembly 9 is installed at the bottom of the rotating plate 8. A conveying assembly 10 is provided inside the housing 1, and a cleaning assembly 11 is installed on the side of the connecting frame 3. The buffer assembly 6 includes a fixed rod 12, which is fixedly connected to the movable plate 4. At the bottom of the movable plate 5, a movable block 13 is slidably connected to the outer side of the fixed rod 12. A buffer spring 14 is sleeved on the outer periphery of the fixed rod 12. The movable block 13 compresses the buffer spring 14 to relieve the pressure on the movable block 13. A connecting rod 15 is rotatably connected to the bottom of the movable block 13, and a clamping plate 17 is rotatably connected to the bottom of the connecting rod 15. The pressure on the clamping plate 17 is transmitted to the movable block 13 through the connecting rod 15. A telescopic rod 16 is installed at the bottom of the movable plate 5, and the clamping plate 17 is fixedly connected to the bottom of the telescopic rod 16. The movable plate 5 moves downward with the clamping plate 17 to clamp the display screen on the fixing frame 4. A buffer pad 32 is fixedly connected to the bottom of the clamping plate 17. The buffer pad 32 is made of rubber and provides initial buffering of the pressure applied to the clamping plate 17.

[0034] Reference Figure 1 , Figure 4 and Figure 5The periodic rotating assembly 9 includes a driven wheel 18, which is fixedly connected to the bottom of the rotating plate 8. Rotating the driven wheel 18 causes the rotating plate 8 to rotate together. A drive wheel 19 is provided at the bottom of the rotating plate 8. A drive column 20 and a limit wheel 21 are fixedly connected to the bottom of the drive wheel 19. The drive column 20 is slidably connected inside the driven wheel 18. The drive wheel 19 drives the drive column 20 into the driven wheel 18, pushing the driven wheel 18 to rotate. When the drive column 20 rotates out of the driven wheel 18, the driven wheel 18 stops rotating due to the cooperation of the limit wheel 21. A storage slot 24 is provided at the top of the rotating plate 8. The cleaned display screen is conveyed into the storage slot 24 for storage. A motor 22 is fixedly connected to the bottom of the support frame 2. The bottom of the drive wheel 19 is fixedly connected to the output end of the motor 22. The motor 22 rotates the drive wheel 19, controlling the operation of the periodic rotating assembly 9. The bottom of the rotating plate 8 is provided with a slot 23, and the support frame 2 is slidably connected inside the slot 23. By setting the slot 23, the position of the rotating plate 8 when it rotates is limited.

[0035] Reference Figure 1 and Figure 3 A cylinder 7 is installed at the bottom of the fixed frame 4. The moving plate 5 is fixedly connected to the output end of the cylinder 7. The moving plate 5 is moved by the cylinder 7, so that the clamping plate 17 clamps the display screen. The conveying assembly 10 includes two rotating columns 25. The outer sides of the two rotating columns 25 are fixedly connected to the wheels 26. The outer circumference of the two wheels 26 is fitted with a conveyor belt 27. The rotating columns 25 rotate together with the wheels 26, controlling the movement of the conveyor belt 27. A motor 28 is installed on the side of the outer shell 1. One of the rotating columns 25 is fixedly connected to the output end of the motor 28. The rotating column 25 is driven by the motor 28, controlling the movement of the conveyor belt 27. The fixed frame 4 is fixedly connected to the surface of the conveyor belt 27. When the conveyor belt 27 moves, it moves together with the fixed frame 4. The cleaning assembly 11 includes a second cylinder 29, which is mounted on the side of the connecting frame 3. The output end of the second cylinder 29 is fixedly connected to an output pipe 30, and the end of the output pipe 30 is fixedly connected to a nozzle 31. The nozzle 31 is installed inside the housing 1. The gas in the second cylinder 29 used to clean the display screen is sent into the nozzle 31 through the output pipe 30 to clean the display screen on the mounting frame 4.

[0036] Working principle: The start cylinder 7 drives the moving plate 5 to move downward with the clamping plate 17, clamping the display screen on the fixing frame 4. When the clamping plate 17 touches the display screen, the pressure applied by the clamping plate 17 is transmitted to the moving block 13 through the connecting rod 15, causing the moving block 13 to move outward and compress the buffer spring 14. The buffer pad 32 made of rubber material relieves the pressure applied to the display screen, expands the force range that can fix the display screen without damaging it, improves the efficiency of fixing the display screen, and protects the display screen from damage.

[0037] To improve the efficiency of collecting and cleaning the displays, motor 22 drives the drive wheel 19 to rotate, which in turn drives the drive column 20 and the limit wheel 21. As the drive column 20 rotates one revolution, it enters the driven wheel 18, pushing the driven wheel 18 and the rotating plate 8 to rotate. When the drive column 20 rotates out of the driven wheel 18, it works with the limit wheel 21 to stop the rotation of the driven wheel 18 and the rotating plate 8. This allows the rotating plate 8 to periodically rotate and switch the collection slot 24, collecting and cleaning the displays that are then transported to the collection slot 24. This improves the efficiency of the display collection process and increases the automation level of the equipment.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
